Last night, the History Channel premiered a documentary, Sex in '69, about the sexual revolution in America. In it, radical feminists of that era reflect on how feminism was shaped by the revolution, and vice versa.

My favorite part about how women were discovering how to pleasure themselves is this lady's face when she's shown a vibrating dildo.

The documentary also talks about the feminist protest of the 1969 Miss America Pageant in Atlantic City, a pivotal moment in the women's movement. Usually, for retrospectives on feminism, we hear a lot from scholarly talking heads who have not only studied and analyzed the movement, but were also part of it. But Sex in '69 featured a lesser-examined — but equally illuminating — viewpoint: that of a 1969 Miss America contestant. In this clip, Susan Anton, Miss California 1969, gives her take on how the protest affected her. Interestingly, 40 years later, she is grateful for women's liberation, and thinks we still have a long way to go.
